("Cantor"), pursuant to which the Company could issue and sell, from time to time, shares of its common stock having an aggregate offering price of up to $10.0 million through Cantor as the sales agent. Cantor could sell the Company’s common stock by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415(a)(4) of the Securities Act.
On August 12, 2022, the Company became aware that the shelf registration statement on Form S-3 (file number 333-231923) (the “Registration Statement”) associated with this Sales Agreement had expired on June 21, 2022. Prior to becoming aware of the expiration, the Company sold an aggregate of 3,117,100 shares of its common stock at the market price, following the expiration of the Registration Statement and through August 12, 2022, for aggregate proceeds of approximately $4,494,496. There was no sale of shares after August 12, 2022. The sale of these shares may be subject to potential rescission rights by certain shareholders. As of September 30, 2022, there have been no claims or demands to exercise such rights. As a result of these potential rescission rights, the Company reclassified 3,117,100 shares, with an aggregate purchase price of $4,494,496 of its common stock as outside stockholders’ equity. The reclassification of these shares shall remain for a period of one year from the applicable transaction date. These shares have been treated as issued and outstanding for financial reporting purposes.
On August 15, 2022, due to expiry of the Registration Statement, the Sales Agreement was mutually terminated. Since the start of the agreement on August 12, 2021, a total of 3,281,067 shares, for gross proceeds of approximately $7.6 million, had been sold pursuant to the Sales Agreement.
